Dear "geo-tectonics" mailing list members,
For more than one month I've been trying to figure out what does it
mean the different westward rates of the two "micro-plates" northeast
and southwest from Louisville Ridge on the picure "Underwater
mountains - rate of destruction" from the article:
BBC NEWS, Science & Environment, "Undersea mountains march into the
abyss", Dec-6, 2011
< http://www.bbc.co.uk/news/science-environment-16056192 >, accessed
Jan-11, 2012.
The NE microplate makes westward 8 sm per year and SW microplate makes
5.5 sm westward per year. Could that mean that not only Tonga Trench
is a convergent boundary, but also Louisville Ridge seamount chain
itself is a convergent boiundary as well?
Could the same convergent mechanism be suggested for Louisville Ridge
as it was suggested for Hawaii in my post:
"Hawaii Convergent, Part 2. Introducing The Concept Of Geofracture
(not Plate) Tectonics."
Thanks,
Sergey D. Sukhotinsky.
